Auto off problem after lollipop update

[Cyrus1]

Hi guys recently i updated my xperia t2 ultra to lollipop and from then on my device has totally become useless. Everytime i turn on my phone it automatically gets off in a few minutes. After doing some research on the internet i ve found out that its not only me having this problem. I request sony to fix this as soon as possible maybe with another update.
Others having the same problem may also join this thread.

I think this is more of a hardware problem maybe the battery than a software problem.

Yes i experience that " Optimising apps" thing everytime i turn on my device.

Indeed, contact your Local support to get your phone inspected

I have the similar problem after I upgraded the OS.

My phone would reboot itself a couple times in the day and it sometimes just turns itself off.

There were times that I did not know it's off and missed calls and messages.

I live in Canada and I got this phone from HK when I was there Aug/2014.

Support of this phone is not available in N. America since I had already sent it back to be serviced in HK once because it could not see any MicroSD card that I put in it.

I would appreciate if anyone out there can share any idea to resolve this, thanks.

Hi! Finally my problem has been solved. I took my handset to the service centre and they replaced my battery. Now it's fine.
